Definitions
- the invention relates to orthopedic devices in aid of bone-fracture repair and, in particular, to a patientoperated device for stimulated transient distraction of fractured components of a bone.
- External fixators of the nature disclosed in U.S. Patents Re. 31,809 and 4,621,627 rely upon an elongate central body of selectively adjustable length, with a bonescrew or bone-pin anchoring clamp at each longitudinal end of the body, with preferably a selectively locked ball-joint connection between each anchoring clamp and the body end to which it is connected.
- Selectively available body length involves telescoping body parts which are keyed against rotation and which can be secured to each other to hold a given setting of longitudinal span between the anchoring clamps.
- a length-adjusting jacking mechanism which may be an accessory device used by the surgeon to periodically adjust overall fixator-body length, in the course of a number of weeks of healing repair of the fracture; the accessory device is detachably applicable to the respective fixator-body parts, for incrementally jacking the fixator-body parts while momentarily releasing the secured relation of these body parts, the secured condition of the body parts being reestablished before detaching the jacking mechanism.
- a patientoperated distraction device for selective periodic distraction of a fractured bone that has been set for retention by an external fixator having an elongate distensible fixator body connected to bone-screw or bone-pin clamps at the respective ends of said fixator body, characterised in
- a device which can be patient-operated without need for external power supply.
- an accessory device which is applicable to existing commercially available external fixators and which is also applicable to a patient who is already fitted with and using an external fixator.
- an external fixator for patient-operated periodic distraction of the fracture.
- FIG. 1 The prior art device of Fig. 1 is generally as shown and described in said U.S. reissue patent, wherein an external axial fixator is seen to comprise an elongate central body 10 of telescopically related inner and outer body parts which can be adjusted as to overall effective length via a clamp bolt 11 which can secure these body parts to each other, for a given selected position of bolt 11 in an elongate slot 12 in the inner body part.
- an external axial fixator is seen to comprise an elongate central body 10 of telescopically related inner and outer body parts which can be adjusted as to overall effective length via a clamp bolt 11 which can secure these body parts to each other, for a given selected position of bolt 11 in an elongate slot 12 in the inner body part.
- One end of one of the body parts e.g., the outer body part 13 has a balljoint connection 14 to clamp means 15 for securely clamped anchoring reference to one or more bone-screws or pins 16 that will be understood to have been driven into bone at offset in one direction away from a fracture in the bone;
- the opposite end of the other body part e.g., the inner body part, has a similar ball-joint connection 17 to similar clamp means 15' for securely clamped anchoring reference to bone screws or pins 16' that have been driven into the bone at opposite offset from the fracture site.
- Both ball joints are selectively lockable, to retain a given angular relationship of the axis of body 10 to the respective axes of clamps 15, 15', as appropriate for particular applications.
- the outer body part 13 has a transverse bore that is adapted to receive and locate a first pin 19 of a length-adjusting accessory 20; and similarly, at the opposite head or balljoint connection end 21, the inner body part has a transverse bore that is adapted to receive and locate a second pin 22 of the accessory 20.
- the length-adjusting accessory 20 comprises an internally threaded outer tubular member 23 which mounts pin 19 at is projecting end, and an inner threaded rod has a wrenchable head 24 at the opposite end.
- the inner threaded rod is wrench-actuated at 24 for adjustment of the extent of thread engagement within tubular member 21, and the head (24) end of the threaded rod seats on and is rotatable within a counterbore of a boss 25 which mounts pin 22.
- a lock nut 26, also engaged to the threaded rod, is run against boss 25 for locked retention of a given overall accessory length, i.e., a given separation of the accessorymounting of pins 19, 22.
- Fig. 2 shows an accessory device 28 of the invention, featuring a manually operable distraction function, in addition to the length-adjustment function described for the prior art accessory device of Fig. 1 .
- insertion pins 30, 31 mount the accessory to the body 32 of an external fixator which is preferably of the axially dynamic variety, suitably as shown and described in said U.S. Patent No. 5,320,622.
- the lower pin 30 is mounted to a boss 33 which is axially located at the head end 34 of an elongate rod or first body part 35 that is in threaded engagement with the bore of an elongate tubular body part 36; and the upper pin 31 is mounted to a sleeve 37 that is axially slidable away from a fixed flange 38 on body part 36, for accommodation of a manually actuated transient distracting displacement of pin 31 with respect to pin 30.
- the mechanism for patient-operation to achieve such distraction is contained within sleeve 37 and is manually driven by a partial rotary cranking actuation of a handle 49, as will be described in greater detail in connection with Fig. 3 .
- a dynamic axial fixator generally as shown in Fig. 2 is obtainable from said U.S. Patent No. 5,320,622.
- overall length of body 32 is established by a bolt 39 which releasably secures a first elongate body member 40 to an elongate intermediate body member 41 at a given relation of longitudinally guided overlap of members 40, 41.
- body member 40 has an enlarged head 42 which is transversely bored to provide for guided insertion of upper pin 31 of the accessory 28, and head 42 will be understood to be equipped with a ball-joint connection 17 to upper clamp structure 15' as described for the prior art in Fig. 1 .
- a second elongate body member 43 has an enlarged head 44 which is transversely bored to provide for guided insertion of the lower accessory pin 30, and head 44 will be understood to be equipped with a ball-joint connection 14 to lower clamp structure 15, as described for the prior art of Fig. 1 .
- a longitudinal guide rod 45 fixed to and projecting beyond the upper end of body member 43 has bidirectionally axial and resiliently snubbed engagement to the laterally offset upper end 46 of intermediate body member 41.
- a short link 47 is pinned on parallel pivot axes in second body member 43 and in intermediate body member 41, wherein the two pivot axes define a geometric plane which is substantially normal to the longitudinal axis of the fixator, namely, wherein the longitudinal axis is on the geometric alignment of ball centers at the respective ball-joint connections 14, 17.
- the outer body part 36 is closed to establish an enlarged cylindrical land 54 for smooth axial guidance of sleeve 37, in its distraction displacement away from abutment with the shoulder or flange 38.
- this closed end comprises a first semicylindrical part 55 that is an integral formation of body part 36, and a second and separate semicylindrical part 56 that is bolted at 57 to secure parts 55, 56 to each other and thus complete the continuity of land 54.
- a rotary cam 59 which may be a cylindrical member or eccentric is mounted for gyrated rotation on a fixed transverse axis 60, involving diametrically opposed cylindrical bearing formations 61, 61' that are journalled in diametrically opposed bearing bores in sleeve 37.
- bearing formations 61, 61' also pass through diametrically opposed short longitudinal slots 62, 62', by means of which cam 59 is rotatable within the head end of the tubular part 36, and it is also keyed against rotation and incrementally axially displaceable in slots 62, 62' .
- Various force-fitted engagements of separate parts in the succession 61, 62, 59, 62', 61' assure an effectively shaft-mounted eccentric at 59, with provision for positive cam actuation via partial cranked rotation of handle 49.
- Fig. 3A illustrates a construction alternative for the actuating end of the accessory 28 that has been described in connection with Figs. 2 and 3 .
- the distal end of threaded body part 35 is seen within the bore of outer tubular body part 36.
- Sleeve 37 mounts the pin 31 by way of an extended shank 31' of pin, extending across the full diameter of the sleeve, with threaded distal-end engagement to the sleeve, as limited by a shoulder formation of pin 31.
- the pin shank 31' freely passes through diametrically opposed openings in tubular body part 36; these openings may be oval, with longitudinal orientation of their major-axis dimension so as to develop a longitudinal clearance 62 for accommodating the axially distracting displaceability of sleeve 37 (and its mounting pin 31) with respect to body member 36.
- 3A may be a cylindrical portion of a unitary part, which further comprises a distal-journal end 63 of smaller diameter, a proximal-journal end 63' of greater diameter, a distal grooved projection 64 for snap-ring retention, and a proximal-end projection 64' for pinned mounting of the handle 49; it is noted (1) that the elements 64, 63, 63', 64' of this unitary part are all on the axis of journal support by sleeve 37, with the axis of cam 59' eccentrically offset from axis 60, to the extent of desired distracting displaceability of pins 30, 31 with respect to each other, and that cam 59' is rotatable (with suitable clearance, not shown) in a transverse diametrically extending cam-following bore near the distal end of body member 36.
- body member 36 is shown to have a solidly closed distal end 36' in which the cam-following bore is formed.
- a spring detent pin 49' carried by handle 49 is detent-engageable at a local detent recess in sleeve 37, to resiliently retain the longitudinally oriented zero-distraction position of handle 49 when not in use.
- the longitudinal span S to accord with points of connection to an installed fixator is adjustably set (at 34), with sleeve 37 seated against shoulder and with cam 59 at its low point in relation to the cam-follower wall 58.
- a partial rotation of the cam, manually imparted by handle 49, will engage cam 59 to wall 58 to effect a transient distraction displacement ⁇ S, as sleeve 37 develops a corresponding incremental axial offset from shoulder 38.
- the handle 49 can allow the fixator to return to its normal axially fixated relation of the involved bone connections, astride the fracture.
- the effective cam rise may be 1 or as much as 2 mm, but preferably the distractioneffecting cam rise is in the range 0.8 to 1.2 mm.
- Fig. 6A is a simplified diagram to indicate present preference that, instead of cam 59 being cylindrical and eccentrically mounted with respect to the rotary axis 60, cam 59 has a somewhat ovate profile whereby to devote an extended proportion of its rise profile to achieving a substantially constant rate of rise, in the order of 4 mm/second between the acceleration rise and deceleration rise needed to complete a given fully distracting displacement stroke of pins 30, 31 with respect to each other.
- this rise is a following of the change of cam (59) profile from a minimum radial extent R 1 to a maximum radial extent R 2 , occurring as shown over a range of approximately 90 degrees of cam rotation between points a and b of the cam profile.
- Fig. 6A is a simplified diagram to indicate present preference that, instead of cam 59 being cylindrical and eccentrically mounted with respect to the rotary axis 60, cam 59 has a somewhat ovate profile whereby to devote an extended proportion of its rise profile to achieving a substantially constant rate of rise, in the
- 6B is a graphical display of distraction displacement as a function of time, showing the presently preferred order of uniform rate (3 to 5 mm/sec) for substantially two-second dwells at each of the cam-following limits R 1 , R 2 , it being recommended that as many as ten recyclings of the indicated uniform-rate program be a typical protocol of patient-operated distraction.
- the described accessory of Fig. 3 lends itself to a more elaborate protocol of use, particularly once the patient has entered the weight-bearing phase of using his dynamic fixator.
- the surgeon may prescribe incremental compressive action at the fracture site by reason of limited axial displaceability to transiently reduce the span S with each weight-bearing step via the fractured but dynamically fixated bone.
- the inner body part 34 is incrementally wrenched so as to reduce the span S in incremental prescribed relief of the sleeve/shoulder engagement; if handle 49 and cam 59 are in the low-point position as shown in Fig.
- any axial clearance of the cam 59 with respect to the cam-follower wall 58 will be opened while the corresponding axial clearance is opened between sleeve 37 and shoulder 38.
- This shoulder clearance is available for the indicated transient incremental compressive action on the fracture site, with each weight-bearing step. And it will also be observed that, even though transient compressive action is available, the manually operated distraction cycle is also available, as long as the rise of cam 59 is sufficient to exceed the above-noted axial clearances.
- transient distraction and/or compression of the fracture site involves transient axial displacement of sleeve 37 with respect to shoulder 38.
- the embodiment of Fig. 4 provides analogous operation by reason of transient axial displacement of an inner body part 65 with respect to an outer body part 66.
- the parts 65, 66 have limited telescopically guided fit, the limitation being axial by reason of a transverse pin 67 between diametrically spaced bores of the outer (tubular) body part 66, wherein pin 67 passes through a limited axial slot 68 of the inner body part 65.
- the mounting hub 71 on pin 69 is shown to be carried at the exposed outer threaded end of body part 65, with nuts 72, 73 for fine setting of a given clamped axial position of pin 69; and the mounting hub 74 of the other pin 70 is shown to be selectively clamped at any given one of plural equally spaced locating grooves 75 (a,b,c) in the outer surface of body part 56, clamping being via three equally spaced set screws 76, only two of which appear in Fig. 4 .
- the manually operated function of transient distraction is a built-in feature of a dynamic axial fixator 80 of the general nature shown for the fixator in Fig. 2 , but without requiring an accessory (28) to perform the transient distraction.
- the head end 44' of the outer body part 43' is slightly more axially elongate than is shown for head 44 of Fig. 2 .
- an idler arm 81 will be understood to be pivoted at 82 to body part 43' on an alignment parallel to and axially offset from the lower pivot for link 47. Idler arm 81 will also be understood to be accommodated within a recess in head 44'.
- link 47 is oriented transverse to the longitudinal axis of the fixator body, and a projection 83 on the adjacent confronting end of intermediate body part 41' is poised for engagement by arm 81, with arm 81 substantially parallel to link 47.
- a rotary cam or eccentric 84 is shown mounted for rotation on a transverse axis, schematically indicated at 85, in head 44'. It will be understood that the cam or eccentric 84 can be shaftdriven on axis 85, by a manual crank, not shown in Fig. 5 but as shown in Fig. 3 or Fig. 4 . Eccentric throw incrementally distracts bone-screw clamp 15' with respect to bone-screw clamp 15.
- the annular body member or sleeve 37 again overlaps and is guided for limited axial displacement on the tubular body member 36; and the fixator-engageable rod 31 derives fixed mounting from sleeve 37, at diametrically opposed locations.
- Rod 31 passes through tubular body member 36 via diametrically opposed slots 62, of sufficient axial extent to provide anti-rotational guidance of body member 36 with respect to sleeve 37 for all cam-driven axial displacements.
- FIG. 7A An important feature of Fig. 7 is the characterizing of cam and cam-follower action, which is further illustrated in connection with Fig. 7A .
- Fig. 7A displays only the cam 30, which is integral with or otherwise fixedly related to a proximal land 81 of greatest diameter and to a distal land 82 of lesser diameter; the land 81 will be understood to derive journal support in a diametrically oriented bore 83 ( Fig. 7 ) through one side of sleeve 37, and land 82 will be understood to derive further journal support in a counterbore (not shown) through the opposite side of sleeve 37, with the operative profile of cam 80 interposed between lands 81, 82.
- Cam 80 is characterized by a flat surface 84 which is normal to a central plane of symmetry through the axis of cam rotation, determined by the aligned centers of lands 81, 82. Outer rounded lobes 85, 85' symmetrically terminate the respective ends of surface 84 and determine an overall cam width W 1 , approximately 75 percent of which is attributable to surface 84.
- the contour of cam 80 is completed by sloping back sides which are respectively tangent to the profiles of lobes 85, 85' and of land 82.
- cam 80 will be recognized in Fig. 7 , in the context of coacting cam-follower structure of the tubular member 36, wherein the drawing illustrates the relation of parts for an instant during the course of a distracting actuation of cam 80, namely, with cam 80 rotated a small fraction ⁇ 1 , of its full range ⁇ 2 of displaceability from a zero-distraction condition wherein the flat surface 84 is normal to the central axis 86 of the tubular body member 36.
- Cam-follower structure is provided by diametrically opposite matching edges 87 of diametrically opposite generally rectangular openings, of body axial length L and transverse width W 2 ; the edges 87 may be said to lie in a geometrical plane that is normal to the central axis 86. Since body member 36 is tubular, the back wall of these rectangular openings is closed and defined by a plate 88, seated against a shoulder and fixed in position by a transverse pin 89.
- the transverse width dimension W 2 slightly exceeds the width W 1 of cam 80, but the length dimension L preferably is less than the width W 1 of cam 80.
- Figs. 8 and 9 is illustrative of such a device, which will be understood to be built into the head end of a tubular outer body member 136; member 136 has adjustably threaded engagement to the elongate stem of an inner body member 135 which carries one of the fixatorengageable pins (not shown in Fig. 8 or 9, but analogous to the showing at 30 in Fig. 3).
- an outer sleeve 137 mounts the other fixator-engageable pin 131 at diametrically opposite locations, with pin 131 passing through axially short slotted openings 162 which establish sufficient longitudinal clearance to accommodate axially distracting displaceability of sleeve 137.
- a cam-follower element 155 in the form of a cylindrical plug is secured by pin means 156 to body member 136, and plug 155 features a transverse bore of generally square section; axially spaced walls 170, 171 of this generally square section provide cam-follower surfaces, for handactuated rotary displacement of a single-piece cam component 172, shown in the form of a crank shaft, in greater detail in Figs. 10A and 10B.
- the cam component 172 is seen to comprise spaced cylindrical bearings 173, 174 which will be understood to derive journal support in diametrically opposite large and small bores in sleeve 137.
- a crank pin element 175 integrally, connects the spaced bearings 173, 174; and a stud formation 177 outward of bearing 173 provides a rugged means of handcrank 149 connection, the same being shown pinned at 178, to retain the connection.
- the stud formation 176 is suitably of square section, engaging a bore of similar square section in handle 149, and a locking pin 177 secures the square stud-to-bore engagement, with Allen-head driven thread engagement in the handle.
- a detent 149' carried by handle 149 provides releasable engagement to a central detent notch in the adjacent end of pin 131, to releasably hold the retracted position of handle 149, parallel to the longitudinal axis of body member 136.
- crankshaft element 172 is configured at its reduced lower-bearing end 174 to permit simple threading assembly of crank pin 175 and bearing 174 regions via the sleeve bore in which the larger bearing 173 is journalled and via the transverse square section bore in plug 155. This assembly is retained by snap-ring engagement to a peripheral groove 178 in the small-bearing end of crankshaft element 172.
- Fig. 13 is a simplified sectional view at a part of handle 149 to show a hinged circumferential clamp 180 secured by a clamp bolt 181 so as to position a stop projection 193 alongside the finger-engageable end of handle 149, thus limiting rotary actuation of handle to a single side of the at-rest position of parallel relation to the axis of body 136, namely, limitation to the side on which manually actuated distraction is possible, to the fully distracted relation depicted in Fig. 11.
- a recommended program of use is for the first week to be one of axial fixation, i.e., no compression and no distraction. Then for the next 4 to 5 weeks, the patient should be instructed to use the distraction feature as a rapid sequence of distraction-displacement cycles, e.g., a sequence of ten cycles each day, wherein the operative throw of cam 172 is in the range 1 to 2 mm (+ ⁇ S).
